Glass polishing and inducing micro marring...

[Paul A.]

Mike, some guidance please when you get time.

I am practicing my glass polishing on my wife's car (of course). Using CarPro Ceriglass and carpro glass pads I've introduced some fine micro scratches consistent with pad rotation. I know I put them there because they weren't there before. This happened on her passenger rear side window (test area).

I've used both my Flex Beast and rotary and practiced your video to a "t". When this happens on paint (compound + wool pad etc.) I know how to remove them. Not so with glass.

Thanks.

Ouch!

This is a problem.


I've only rand into this one other time in my life and it was when mixing brands for pads and products. This is why in any video or article I specifically state if a company makes a polish and also offers a pad - then buy both from the same company - to reduce the risk of a problem like this.

At least this isn't happening on the driver's side of the windshield.

Here's the only help I can offer,

1: Re-check to make sure everything is clean and try again.

2: Shake the product well before use and during use.


The other thing you can try is troubleshooting. To do this you would test your process on different class, as in a different window or different car.


One more thing you can do is contact CarPro directly. See if they have any suggestions. I'm not sure how long Ceriglass has been around but it's been a few years.

Normally if this type of thing has happened to other people, it's common to contact the manufacturer meaning they may have a database of such issues and also a remedy.


Do keep us updated.

Thank you, Mike. Will do.

I know Tampa is a bit a drive to Stuart, but if you want to drive over here I'll do my best to help you recover.

It will have to be after my upcoming class.


By the way, we're machine polishing glass on two cars in this class.


SHOCK and AWE Detailing Class! TOOLS - TOOLS - TOOLS!


We shot a brand new glass polishing video just last Thursday using this 1957 Chevrolet Corvette for MTE Mobile Tech Expo - no problems.






And the owner of this 1970 Ford Mustang Mach I says the windshield is so bad it's dangerous to drive at night.

Thanks again, Mike!!! Yes, a bit of a drive but i sincerely appreciate the offer.

As a side note, your vid's lately have piqued my interest regarding glass polishing. GREAT stuff and thanks for all of it. Trying to work in an upsell but not before i perfect it.

Be sure to keep the Ceriglass damp. Do not dry buff.

Copy that. I feel your pain. And I think Ron makes a great point too - stay liquid when buffing.


A few years ago we buffed the scratches out of the passenger side window glass on a first generation Camaro. Real bad ass big block car. No problems. So I know it can be done.

I normally teach "The Buddy System" when polishing glass. That is have a buddy nearby and have them mist a little water onto the glass as you're buffing. It's faster this way.


See me misting some water while my student buffs?

When machine polishing glass it helps to have a buddy to mist a little water while you're buffing because glass polishes tend to dry up quickly. This works best with a water sprayer that really does a good job of atomizing the water into a fine spray as this dramatically reduces any splatter mess.

I never found time to do a full write-up but here's an Audi, I forget if it's an R8 or R10?

Owner's buddy put about a 1" scratch in the back window. Took me about 3-4 hours but I sanded it out and then buffed out my sanding marks.






See the owner misting my work area with SONAX glass cleaner?

Mike,

Thanks for the extensive write-ups on this.

I'm guessing that it's the heat build-up that dries out the product.

Also, are there expiration dates on this stuff?
